Dual Diagnosis Treatment in Jacksonville: Mental Health and Substance Use Together

What dual diagnosis means

Dual diagnosis means a person has both a mental health condition and a substance use disorder. Professionals usually call these co-occurring disorders. According to SAMHSA’s page on co-occurring disorders, the term can cover any combination of the two, and no one pairing defines it.

It is common. SAMHSA reports that about 21.2 million U.S. adults had both a mental illness and a substance use disorder, based on its 2024 National Survey on Drug Use and Health. SAMHSA also says people with mental illness are at higher risk of developing a substance use disorder.

If your family is dealing with this, you may have heard two different stories. One doctor says the drinking is causing the depression. Another says the depression is causing the drinking. Both can be partly true, and treatment doesn’t have to wait until you know which came first.

Why treating both matters

Substance use and mental health conditions tend to feed each other. Someone may drink to quiet anxiety, then wake up more anxious and drink again. If treatment only deals with the drinking, the anxiety is still waiting. If it only deals with the anxiety, the drinking keeps undoing the progress.

A program that says it treats dual diagnosis should be able to explain how. Some programs use the phrase in their marketing but have little mental health staff. These questions will show you the difference:

• Is a psychiatrist or psychiatric nurse practitioner part of your team, and how often will my loved one see them?
• Do your counselors have training in mental health as well as substance use?
• Will one plan cover both conditions?
• Can you continue the psychiatric medications my loved one already takes?
• What happens if a mental health crisis comes up during treatment?

Medications need care here

SAMHSA warns that combining medicines used to treat substance use disorders with anxiety medicines such as benzodiazepines (Xanax, Valium or Klonopin) can have serious side effects. That doesn’t mean anyone should stop them. It means every prescriber needs the full list. Our page on medication-assisted treatment (MAT) explains those medicines.

This page is general information, not medical advice. Please talk with a doctor before making any change to medications or substance use.

Which level of care fits

Dual diagnosis care can happen at any level. A serious or unstable mental health condition may call for inpatient rehab or partial hospitalization (PHP). A stable condition may do well in intensive outpatient (IOP) or outpatient rehab, alongside a psychiatric provider. Our 2-minute level of care guide can help you start, and aftercare should cover both conditions.

If there is a crisis in Florida

Florida has two separate laws for involuntary help. The Baker Act is about mental health emergencies. The Marchman Act is about substance use. Our guides explain when each one applies. Some groups need extra thought, too, and our first responder and Veteran guides cover trauma.
